Sounds like you were using the wrong or a corrupt file.

Welcome to Android Central! Did the bootloop start before or after installing the update? Did you root the phone, and have you been modifying it with various ROMs?

[James Ndubuisi]

The boot loop started after an OTA update, the phone didn't turn off during update because of low battery or so, after the update. The boot loop issue started

[James Ndubuisi]

It is not rooted and the phone has never been modified since purchase. I was trying the update through an SD card to fix the boot loop issue

[James Ndubuisi]

I have tried installing the stock room through sd card and an update file but same "wrong footer, signature verification issue". Is there a way I can get a legit update file if the one I'm using is wrong or a signed stock rom?

[B. Diddy]

How old is the phone -- is it still under warranty? Since this was an official system update from Infinix, they should be responsible for any problems it causes. Try contacting their support: https://www.infinixmobility.com/care/support

[James Ndubuisi]

It was bought early last year, I don't think it's still under warranty. Is there another way I can fix it?

[James Ndubuisi]

And sincerely the warranty process in my country is not something I've seen work before. I will prefer fixing it myself.

[B. Diddy]

Ok, it's still worth contacting their support to see if they can help with reflashing the stock ROM in a bootlooped phone. Another good resource would be the forums at XDA-Developers.com.

Thank you sir. Is there a way I can get the signed stock rom or update file

[James Ndubuisi]

I downloaded some from some sites and forums talking about using miracle box Qualcomm flash software and some other software but all attempts failed and it seems the version of files I have isn't signed, an infinix forum said I should back up the rom of an existing phone of exactly same model or update file and use but can't find one

Thank you sir. Is there a way I can get the signed stock rom or update file

Hi, best place is to ask on XDA forum , im not sure you'll get much help here as its not as popular as Samsung, Google, LG etc

You might have to flash through adb commands.

[James Ndubuisi]

Adb is showing unauthorized because debug isn't enabled or so I heard

[James Ndubuisi]

Thank you sir. I'll ask at XDA forum
